Application filed February 2:, me. Serial no. 90,094.

This invention relates to refri household units, particularly of t usedto refrigerate ice for table use, and an object of this being to providea novel, and

crating highly efiicient non-complicated apparatus,

conveniently arranged to use prepared solidified carbon dioxide snow asthe refrigerant. For further comprehension of the invention, and of theobjects, and advantages thereof, reference will be had to the followingdescription and accompanying drawing, and to the appended claims inwhich the various novelfeatures of the invention are inore particularlyset forth.

Referring to the drawing I which forms a part of this disclosure:

Fig. 1 is a horizontal sectional on the lime ll of Fig. 2. a

Fig. 2 is a vertical on the line 22 of Fig. l.

Fig. 3 is a top detailed view of tlielower drawer.

Fig. 4 is a modification illustrating the employment of means to aidin-the opening of the drawer.

Fig. 5 is a view similarto Fig. 1, but of a modified construction.

i of rectangular crosssection,'and at the upper central portion isprovided with a' sunk-in portion 10 to support and house a receptacleinserted'therein, such as 11 formed with projections 11 from the sidestherefor to obtain a clearance space between the walls of the receptacleand the housing 10. i

The refrigerant is placedsin the receptacle 11, and the refrigerant usedis prepared so lidified carbon dloxide snow, which may be entered intothe snow receptacle by eans of a nozzle entering into the mout 11",which thereafter is closed, said nozzle being connected to a supply ofliquid carbon dioxide, with the necessary control valves in: terposed,The liquid carbon dioxide must be under a high pressure, and itsexpansion through the nozzle from high pressure to a -gasat atmosphericpressurea'refrigerates a certain portion into carbon dioxide snow.. Thesnow thus formed being /porous,

- then be compressed to 'obtain a may greater amount in-a giyen'spa'ce,to a density even greater than we. t x b Upon the absorption of heat bythe snow it turns into a gas, and the receptaclell e type radiate theView taken ed within this chamber is a drawer 20, disectional viewtaken' 17 closed. The

is provided .with a plurality of apertures 11 in the side walls andbottom thereof, to allow the escape of the said gas. a v

The inner space of the housing 10, is partially filled with brine 14,which .surrounds the sunk-in? portions 10, to better coolness, and thisbrine may be entered by means of a suitable inlet pipe, and unionindicated. at 15, the faucet 16 being provided at the bottom portion. ofthe housing holding the brine, to permit of removing the same.

It is known that heat rises, speaking coldness and relatively falls,

formed, which has a door 17, hingedas at 18, and at the upper endprovided with lockmg means, 1ndicated'at'19. Slidably' mount vided bypartitions 21 into a plurality of compartments opened at 'the top. Y

The drawer. 20 may he slid out, and these compartments filled withwater, thereafter the drawer being reinserted, and" the door water maythus be frozen: into cubes of ice, which may be used for table purposes.I 1

lnithe modification illustrated in Fig. 4 means is provided toautomatically pro ect the drawer 20 when the door 17 is opened,

the drawer 20' being of shorter length than v the housing so as toprovide a space in the tached thereto against a flange 23, and anadjustable resistance formed by a flange '24 to which the spring istherefore in the bottom of the housing 10, a chamber 10 is .rear for theaction of a spring 22, co-acting between the rear of the drawer, being.at-

tend the. full length of the device, and the brine being stored on bothsides of the chamber in suitable compartments 10*;

The functioning of this device is very ob vious from the abovedescription.- '1

While we have illustrated and described our invention with some degreeof particularity, we realize that in practice various alterationstherein may be made. We therefore reserve the right and privile changingthe form of the details 0 con-- struction, or otherwise altering thearran ement of the correlated parts, without] ,e-

2 parting from the spirit or the scope of the appen (1 claims.

Having thus described our invention,

what we claim as new, and desire to secure by United States LettersPatent is 1. A refrigerator household unit, adapted to refrigerate icefor table use, comprising a housing of rectangular cross-section, having at the upper portion a sunk-in member, supporting a receptacle housingprepared solidified carbon dioxide snow, and provided with apertures toallow the escape of gas, said housing being formed with a brine chambersurrounding the sunk-in member, and a lower chamber, closed by a door,and housing a drawer with partitions to hold water to be turned into icecubes, and means to project said drawer upon the opening of. said door.

2. A refrigerator household unit, adapted to refrigerate ice for tableuse,comprising a housing of rectangular cross-section, having at'theupperv central portion'a sunk-in member, supporting a receptacle housingprepared solidified carbon dioxide snow, and

provided with apertures to allow the escape of gas, said housing beingformed with a brine chamber surrounding the sunk-in member, and a lowerchamber, closed by a door,'and housing a drawer with partitions to holdwater to be turned into ice cubes, and means to project said drawer uponthe opening of said door, said means consisting of a spring actingbetween said drawer, and an adjustable resistance.

3. A refrigerator household unit, adapted to refrigerate ice for tableuse, comprising a housing of rectangular cross-section, having at theupper central portion a sunk-in member, supporting a receptacle housingprepared solidified carbon dioxide snow, and provided with apertures. toallow the signatures.

escape of gas, said housing being formed with a brine chambersurrounding the sunkin member, and a lower chamber, closed by a door,and housing a drawer with partitions to hold water to be turned into icecubes, and means to project said drawer upon the opening of said door,said means consisting of a spring acting between said drawer, and anadjustable resistance, formed by a stud acting in a threaded aperture insaid housing, and a co-acting lock nut.

4. A refrigerator household unit, adapted to refrigerate ice for tableuse, comprising a housing, a sunk-in portion provided in said housing, areceptacle housing prepared solidified carbon dioxide snow supported-insaid sunk-in member, abrine chamber sur. rounding said sunk-in portion,a lower chamber formed in said housing, a door communicating with saidlower chamber, a drawer formed with partitions housed in said lowerchamber, and means to project said drawer upon the opening of said door.

5. A refrigerator household unit, adapted to refrigerate ice for tableuse,comprising a housing, a sunk-in portion provided in said housing, areceptacle housing prepared solidified carbon dioxide snow supported insaid sunk-in member, a brine chamber surrounding said sunk-in' portion,a lower chamber formed in said housing, a door communicating with saidlower chamber, a drawer-formed with partitions housed in said lowerchamber, and means to project said drawer upon the opening of said door,said means consisting of. a spring. acting between said drawer, and anadjustable resistance.
